It's literally all technique and it's all in your feet. You have to clamp the rope with your feet so that you could almost take both hands off the rope. You then work your way up like a catepillar with your legs doing all the pushing. Here is a link that shows the feet. The USMC does a lot of rope climbing on their obstacle courses so try checking some of their sites. I hope this helps, and I'm sorry if that wasn't your question.
